Well, if we are at Vivid period of the Nanoha timeline the TSAB can make essentially much more basic quasi-unison devices called hybrid intelligent devices (or autonomous-action intelligent device). Which seem much lower spec than full unison device but can do some limited form of what Unison devices do (i.e. merging with their users to provide much better finer control and responsiveness for example), but on the other hand it seems they are much easier to use and much more usable in that the need for compatibility isn't present afaik.Just realized that the Bureau is going to be rather shocked at the news that Shipwright can casually make Unison Devices, which even Hayate hasn't been able to do; Reinforce Zwei was built using lefotvers from Eins, without a true understanding of how the tech works.
But yeah. TSAB will be interested nonetheless.
